COMBINED SEEDER AND HAR ROW.

SPBCIFICAIIQN forming part of Letters Patent No. 345,289, dated July13,1886.

Application filed November 21, 1885. Serial No. 153,569. (No model.)

To all whom it may concern:

Be it known that I, EZRA EMMERT, a citizen of the United States,residing at Dixon, in the county of Lee and State of Illinois, haveinvented certain new and useful Improvements in a Combined Seeder andHarrow; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

My invention has reference to combined seeders and harrows, and pertainsmore especially to a new mode of oscillating the stirring-shaft in theseed-hopper, and other improvements in the machine, hereinafterdescribed and claimed.

In the drawings, Figure l is a plan view of a machine embodying myinvention. Fig. 2 is a partial rear elevation thereof. Fig. 3 is a viewof the inner side of the driving-wheel, showing the trip D, which isattached to the end of the stirring-shaft of the seed-hopper, and therelation of such trip to the actuatingstuds formed on the inner face ofsuch driving-wheels B. Fig. 4. is a crosssection of the center of theseed-hopper with the lid thereof raised. Fig. 5 is a cross-section ofthe upper portion of such hopper with the lid closed.

In its general construction my invention involves a seeder of anydesired width to be drawn by two or four horses, as the width of suchseeder may be more or less. connected with the rear of such seeder is aharrow of the lateral width of the seeder, composed of two or moresections, as the width desired in any instance may be.

A is the seed-hooper, supported on the axle B of the carrying-wheels B.

O is the usual stirring-shaft, passed longitudinally through the hopper,and provided with stirrers O to keep the seed-holes free from rubbishand the seed in agitation. The stirrers U are formed with a concavehead, 0 which fits against the lower side of the shaft G, and is held inplace by means of a bolt, 0, passed vertically upward through saidstirrer and shaft and provided with a nut seated on the upper side ofsuch shaft.

The advantage Detachabl y of this construction is that the stirrers, incase of breakage, can be removed and others substituted without removingthe shaft 0. The latter shaft consists of two equal sections, eachsection being journaled in the end of the hopper and in a partition, A,in the center thereof. On the outer end of each section of said shaft 0,and outside of the hopper A, is rig-' idly attached the trip D, thelatter formed with one lug, 1, extended vertically downward, and curvedslightly to the rear, and side lugs, 2 2, curved downward laterally,inwardly, on each side of the lug 1.

E E E constitute the outer series of studs, and E E E the inner series,which project horizontally from the inner face of the carrying-wheels B,and alternately engage the trip D, and thereby oscillate the shaft 0. Inthe outward rotation of the wheel B the inner stud, E, strikes the lug 1and drives to nearly the horizontal. This throws the back of one of thelugs 2 upward in position to be engaged by the next stud E, when thetrip D will be driven back to its original position.

The purpose in providing two lugs, 2, is to afford means for theinverting of the shaft 0 in backing up, and to cause the stirrers insuch backing up to project upward and suspend their operation. Theadvantage of this mode of oscillating the shaft 0 is that it results ina series of sudden impulses, which has the effect of more uniformlydischarging the seed.-

Hitherto difficulty has been experienced by dirt working into the openend of the hub B of the wheels B, and in attempting to avoid thiswashers have been placed at the outer end of such hubs; but the latterhave an outward taper, and the dirt and dust sliding outward on such hubsifted between the washer and hub down to and upon the spindle. Toovercome this inconvenience, I have provided a sandcap, B theinner edgeof which projects slightly under the outer end of the hub B ,'like thelap of a shingle roof, and descendingdust from the hub B falls upon thesand-cap B and from the latter is thrown to the ground, and thusprevented from entering the central cavity or box of the hub.

F is a vertical lever pivoted at F against the rear side of the hopperA, and having its upper end adapted to be grasped, and its lower endinserted in a hole formed in the rear extension, F of the usualgage-plate in the bottom of the seed-hopper. This plate has holestherein corresponding to the seed-holes in the hopper, and by movingsuch plate endwise the seed-holes of the hopper may be more or lessclosed, so as to regulate the discharge of the seed. The provision andfunction of this gage-plate is common, and the usual mode of gaging itwas by a ratchet and spring at the upper end of the lever, correspondingto my lever F. The defect of this mode is that the spring of such leverand the wear at its pivotal point allows some play or variation at thelower end of such lever, and as the machine is sometimes used for sowingsmall seeds such variation allowed to the gage-plate was objectionable.To obviate this difliculty, I provide a plate, G, having a verticalslot, G, and attached by a vertical bolt, G", passed through such slotto aledge on the rear of the hopper A, and when the gage-plate is set toany desired position by moving the plate G against the extension F ofsuch gage-plate and fastening the bolt G such gage-plate is held fromchanging its position.

The lever F is provided with the lip F which engages and holds the lid Aof the hopper when closed.

A is the lid of the hopper A, and there is pivoted to the under sidethereof the folding brace H, the lower end of which is bent laterallyand inserted in the slot A in the partition A, and the extreme end ofsuch brace bent slightly downward to prevent the casual withdrawalthereof. A recess, A, is formed in the forward end of such slot, inwhich, when the lid A is raised, the lower end of the brace drops andsupports the lid. When it is de sired to close the lid, the lower endof.such brace is raised from the recess A and allowed to slide to therear of such slot, as'shown in Fig. 5, and the lid allowed to close.

K is the front draw-bar, attached to the machine by means of rods K,passed to the rear under and suitably attached to the axle B, and towhich rods K the hopper A can be fastened by vertical cleats, throughthe lower ends of which therods K can be passed. The draft is applied atthe clevises K and may consist of either two or four horses. By thismode of draft the sides of the seeder are prevented from oscillating,and are kept at right angles with the line of draft as distinguishedfrom the lateral oscillation consequent from drawing in the usual modeby an evener pivoted on the tongue. Chains L L are attached to therespective ends of the draw -bar K, passing diagonally inward and underthe axle'B, and attached to the rear draw-bar, M, of the sections N. Bythis rearward convergence of the chains L L the sections of the harroware caused to follow precisely the movement of the draft, andparticularly in turning or moving in a cirole, the harrow, instead of,as is usual, turning on a pivot, describes the arc of movement of theseeder. If preferred, the draw-bar K can also be pivoted on the tonguein the usual way.

The effect of the oscillation of the stirrcrs,

as distinguised from their rotation, is to keep the refuse on the top ofthe grain, and here it can be easily removed on replenishing the seed.The rear draw-bar, M, is not indispensable, for the chains L can beconnected directly to the sections N.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, 1s-

1. The combination of the stirring-shaft O, stirrers 0, provided withthe concave head 0", and the bolt 0', substantially as shown, and forthe purpose described.

2. The shaft 0, the trip D, provided with lugs 1 and 2, and thecarrying-wheel B, provided with the two series of studs E and E, adaptedto alternately engage such trip andthusoscillatesuchshaft,substantiallyasshown, and for the purposedescribed. r

3. The combination of the lever F, hopper A, plate G, provided with theslot G, bolt G and the usual gageplate provided with the extension F,substantially as shown, and for the purpose described.

4. The combination of the front draw-bar, K, chains L L, and reardraw-bar, M, such chains converging toward the rear, and thus attachedto the interior portion of such rear draw-bar, substantially as shown,and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

EZRA EMMERT.
